Get Latitude and Longitude from Google Places Autocomplete in React Native - react-native

Question

I've implemented autocomplete for my address field, but the json returned from the Google Maps Places Autocomplete doesn't include the geocoded coords for the places.
There are some answers out there that don't seem to fit. For instance, this one refers to things like google.maps.places.Autocomplete(input, options); which I don't think is a thing in React Native.
Other answers appear to be based on react-native-google-places-autocomplete, but I've implemented this myself and I'd love to not do it again using that module.
Here's my method where I call the API.
async handleAddressChange() {
const url = `https://maps.googleapis.com/maps/api/place/autocomplete/json?key=${GoogleAPIKey}&input=${this.state.address}`;
try {
const result = await fetch(url);
const json = await result.json();
this.setState({ addressPredictions: json.predictions });
} catch (err) {
console.error(err);
}
}
setAddress(prediction) {
this.setState({ address: prediction.description, showPredictions: false });
}
The API response doesn't have any place or geometry property on it:
Object {
"description": "1234 Some Avenue Northeast, Washington, DC, USA",
"id": "4c79fba1b3a5ad33478b79b54896a75a4d56ca53",
"matched_substrings": Array [
Object {
"length": 4,
"offset": 0,
},
],
"place_id": "ChIJneQ1fBO5t4kRf8mTw4ieb4Q",
"reference": "ChIJneQ1fBO5t4kRf8mTw4ieb4Q",
"structured_formatting": Object {
"main_text": "1234 Some Avenue Northeast",
"main_text_matched_substrings": Array [
Object {
"length": 4,
"offset": 0,
},
],
"secondary_text": "Washington, DC, USA",
},
"terms": Array [
Object {
"offset": 0,
"value": "1600",
},
Object {
"offset": 5,
"value": "Maryland Avenue Northeast",
},
Object {
"offset": 32,
"value": "Washington",
},
Object {
"offset": 44,
"value": "DC",
},
Object {
"offset": 48,
"value": "USA",
},
],
"types": Array [
"street_address",
"geocode",
],
}

Answer 1

I have found a solution for the same-
Just use like this-
<GooglePlacesAutocomplete
GooglePlacesDetailsQuery={{ fields: "geometry" }}
fetchDetails={true} // you need this to fetch the details object onPress
placeholder="Search"
query={{
key: "API_KEY_GOES_HERE",
language: "en", // language of the results
}}
onPress={(data: any, details: any = null) => {
console.log("data", data);
console.log("details", details);
console.log(JSON.stringify(details?.geometry?.location));
}}
onFail={(error) => console.error(error)} />

Once you have the place id (ChIJneQ1fBO5t4kRf8mTw4ieb4Q for the example in your question), you can do a place details request.
Make sure you include the Places library in your API call: https://maps.googleapis.com/maps/api/js?libraries=places and a valid API key.
function initialize() {
var map = new google.maps.Map(document.getElementById('map-canvas'), {
center: new google.maps.LatLng(0, 0),
zoom: 15
});
var service = new google.maps.places.PlacesService(map);
service.getDetails({
placeId: 'ChIJneQ1fBO5t4kRf8mTw4ieb4Q'
}, function(place, status) {
if (status === google.maps.places.PlacesServiceStatus.OK) {
// Create marker
var marker = new google.maps.Marker({
map: map,
position: place.geometry.location
});
// Center map on place location
map.setCenter(place.geometry.location);
}
});
}
initialize();
#map-canvas {
height: 160px;
}
<div id="map-canvas"></div>
<!-- Replace the value of the key parameter with your own API key. -->
<script async defer src="https://maps.googleapis.com/maps/api/js?key=AIzaSyCkUOdZ5y7hMm0yrcCQoCvLwzdM6M8s5qk&libraries=places&callback=initialize">
